Description

COMMUNICATION SYSTEM AMONG TOY ROBOTS USING MESSENGER AND TOY ROBOT LINKED WITH THE SAME

Technical Field

[1] The present invention relates to a communication system between toy robots and a toy robot used therefor. More specifically, the invention relates to a communication system between toy robots utilizing a messenger and a toy robot used therefor. Background Art

[2] Recently, according to abrupt expansion of using the Internet, most of computer users, including students, office workers, and the like, use a variety of Internet services, such as an e-mail, web surfing, chatting, and the like.

[3] Among these, a variety of data transmission services, such as chatting or Internet dialog, e-mail, e-card, messenger service, bulletin board, Internet commercials, and the like, is widely used.

[4] Particularly, the chatting service is a service, in which a plurality of users connected to a chatting server chats with other connectors by exchanging texts using the chatting server and a chatting program implemented with common gateway interface (CGI) or the like. The e-mail or messenger service is a service, in which digital data, such as texts, images, and the like, selected by a sender is transmitted to a computer system of a counterpart via a mail server or a messenger server, or not via a server.

[5] For the chatting service, a user connects to a chatting server through a web browser or connects to the chatting server by executing a separate chatting program installed in a client computer. Next, after selecting a counterpart to chat with by opening a chatting room or designating a specific user, if the user inputs a desired text message into a text input window, the text is transmitted to a computer system of the selected chatting counterpart, and a message is displayed thereon.

[6] Such a chatting service is performed using a so-called messenger program.

[7] Meanwhile, going beyond exchanging only text messages, the chatting service performs even a messaging function that expresses user's feelings or the like, for which a special character set known as an emoticon is frequently used.

[8] For such an emoticon, text-oriented character emoticons or predetermined image emoticons are used. Further, it goes as far as to create unique individual emoticons using image emoticons to express user's feelings.

[9] However, if only character or image emoticons are used for chatting, transferred are only two-dimensional visual feelings that are displayed on a monitor, and thus there is a limitation in expressing realistic senses that can three-dimensionally transfer counterpart's feelings.

[33] Hereinafter, the preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

[34] FIG. 1 is a conceptual view showing a communication configuration between toy robots utilizing an instant messenger according to the present invention.

[35] FIG. 1 shows a most preferable embodiment, and the configuration of each embodiment is described below referring to FIG. 1.

[36] As an embodiment, a communication system between toy robots utilizing an instant messenger according to the present invention comprises user terminals Al and Bl 110 and 120, an Internet network 150 allowing Internet communications between the user terminals Al and Bl 110 and 120, and a toy robot A2 130 connected to the user terminal Al 110.

[37] As another embodiment, a communication system between toy robots utilizing an instant messenger according to the present invention comprises user terminals Al and Bl 110 and 120, an Internet network 150 allowing Internet communications between the user terminals Al and Bl 110 and 120, and toy robots A2 and B2 130 and 140 respectively connected to the user terminals Al and Bl 110 and 120.

[38] The different between the two embodiments described above is whether either of the user terminals Al and Bl 110 and 120 has a toy robot A2 or B2 130 or 140, or both of the user terminals Al and Bl 110 and 120 respectively have a toy robot A2 or B2 130 or 140.

[39] The user terminal Al 110 communicates with the user terminal Bl 120 through the

Internet network 150. Particularly, they exchange instant messages using an instant messenger program (not shown). Messages related to emotional expressions, which are included in the instant messages, are converted into control signals of the toy robots A2 and B2 130 and 140 to control operations of the toy robots A2 and B2 130 and 140 or to output audio signals.

[40] Here, the toy robots A2 and B2 130 and 140 can be respectively connected to the user terminals Al and Bl I lO and 120 through a short or long distance wired/wireless communication network. In the case of a short distance communication, a universal serial bus (USB), Bluetooth, or Zigbee communication can be used, whereas in the case of a long distance communication, a wired/wireless Internet communication can be used.

[41] FIG. 2 is a block diagram showing the configuration of the user terminal shown in

FIG. 1.

[42] As shown in the figure, besides basic components 210 of the terminal, each of the user terminals Al and Bl I lO and 120 includes an instant messenger program unit 220, a communication program unit 230, a network communication unit 240, and a connection unit 250.

[43] The instant messenger program unit 220 exchanges instant messages through the network communication unit 240 or analyzes the instant messages/commands and transfers the analyzed instant messages/commands to the communication program unit 230. The detailed configuration of the instant messenger program unit 220 will be described below referring to FIG. 3.

[44] The communication program unit 230 converts the messages transferred from the instant messenger program unit 220 into commands to control the toy robot A2 and B2 130 and 140, converts again the converted commands into control signals of the toy robot A2 and B2 130 and 140, and transfers the control signals to the toy robot A2 and B2 130 and 140.

[45] Here, the control signals are converted into bit signals and audio frequency signals.

Examples of converting the control signals will be described below referring to FIG. 5.

[46] The network communication unit 240 is a module for Internet communications, and the connection unit 250 is a port physically connected to the toy robot A2 and B2 130 and 140.

[54] The chatting counterpart management module 360 manages chatting counterparts of the instant messenger, and the inter-heterogeneous messenger message conversion module 370 operates as a module for providing message compatibility between heterogeneous messengers.

[55] FIG. 4 is a block diagram showing the configuration of the toy robot shown in FIG.

1.

[56] As shown in the figure, each of the toy robots A2 and B2 130 and 140 includes a control unit 410, a terminal connection unit 420, a driver unit 430, a sensor input unit 440, a sound input unit 450, a sound output unit 460, and a memory unit 470.

[57] The control unit 410 performs general controls over the toy robot A2 and B2 130 and 140. The terminal connection unit 420 is a medium that is physically connected to the user terminal, and the memory unit 470 is a module for storing and executing programs.

[58] The sensor input unit 440 and the sound input unit 450 are input units that directly receive input signals from a user, which can be additionally included in the present invention.

[59] If an external signal is inputted through the sensor input unit 440 or the sound input unit 450, the signal is transferred to the messenger of the counterpart user terminal B 1 120 in the form of an instant message through the messenger of the user terminal Al 110. The transferred instant message is converted into a control signal for controlling the toy robot B2 140 by the communication program unit 230 of the user terminal B 120 and drives the driver unit 430.

[60] The driver unit 430 is for driving the toy robot, which is generally a motor. The sound output unit 460 performs a function of a speaker or the like for outputting sounds.

[61] The driver unit 430 drives the toy robot in response to a control signal transferred from the communication program unit 230 included in the user terminal, and objects to be driven can be configured in a variety of ways. That is, various parts of the toy robot, such as arms, legs, eyes, head, body, waist, and the like, are electrically connected to the driver unit 430, and each part can be operated by a control signal transferred from the communication program unit 230.

[62] In the same manner, the sound output unit 460 outputs emotional expression as a sound in response to a control signal transferred from the communication program unit 230 included in the user terminal.

[63] The memory unit 470 is an optional constituent, which stores a separate communication program unit 230 for implementing the toy robot according to the present invention if the instant messenger program unit 220 is previously installed in the user terminal.

[64] Here, the control signal being transferred is divided into a bit signal and a frequency

(audio) signal as described above.

[65] At this point, if the bit signal is transferred, the bit signal is divided into a signal for operating the toy robot and a signal for outputting sounds. Further, the signal for operating the toy robot is subdivided into signals for driving each part of the toy robot.

[66] If the frequency signal is transferred, a stereo sound channel is used. One channel is used as a sound channel for outputting sounds through the sound output unit 460, and the other channel is assigned for a control frequency signal and connected to the driver unit 430 to control operations of the toy robot.

[67] It goes without saying that the configuration of the toy robot should be changed according to whether the control signal of the toy robot is a bit signal or a frequency signal.

[68] FIG. 5 is a conversion table showing an example of converting instant messages into robot control signals (bit signals) according to the present invention, and FIG. 6 is a graph showing frequencies of a toy robot control signal (an audio signal) converted from an instant message according to the present invention.

[69] As shown in FIG. 5, an instant messenger message or a command is converted into a toy robot command through the communication program unit 230 by way of the instant messenger program unit 220, and a robot control signal is transferred to the toy robot according to the toy robot command.

[70] An instant message/command '/HAHA' is converted into a toy robot command 'Sl', and a toy robot control signal '00 1101000' is transferred according to 'Sl'. The toy robot is driven or a sound is outputted in response to the toy robot control signal '00 1101000'.

[71] The first two bits of the toy robot control signal indicate whether the toy robot control signal is a signal for driving the toy robot or a signal for outputting sounds. The other bits are used as a signal for driving each part of the toy robot.

[72] Referring to FIG. 6, it shows a transfer mode of frequency signals (audio signals), and a stereo channel is used here.

[73] One channel is used as a sound channel, and an audio signal is outputted as is as a sound through the sound output unit 460. The other channel is used for driving control signals (a first to a third driving frequency signals).

[74] As for the driving control signal, an instant messenger message or a command according to user's input and UI handling is converted into a toy robot command (hereto, it is the same as the bit signal transfer mode), converted into the shown first to third driving frequency signals according to the toy robot command, transferred to the toy robot, and controls driving the toy robot.

[75] It goes without saying that the detailed configuration of the toy robot is changed according to the bit signal transfer mode or the frequency signal transfer mode, and details thereof are apparent to those skilled in the art and will not be described here.

[76] In addition, the converted control signals shown in FIGS. 5 and 6 are simplified for explanation, and the present invention is not limited to these signals.

[77] FIGS. 7 to 9 are views showing examples of communications between toy robots u tilizing an instant messenger according to the present invention.

[78] Referring to FIG. 7, if the instant messenger 620a of the terminal Al 610a transfers an emotional message (7HAHA') to the instant messenger 620b of the terminal Bl 610b, the instant messenger program unit 220 of the terminal B 1 610b displays the message on the window of the instant messenger 620b in the form of an emoticon, and the communication program unit 230 converts the message into a toy robot command (refer to FIG. 5) and a toy robot control signal (refer to FIGS. 5 and 6) and transfers the converted signals to the toy robot B2 600b.

[79] Subsequently, the toy robot B2 600b expresses the counterpart's emotional expression message as a motion or a sound through the control unit 410, driver unit 430, and sound output unit 460 in response to the robot control signal.

[80] Referring to FIG. 8, if the instant messenger 720a of the terminal Al 710a transfers a melody message (712345') to the instant messenger 720b of the terminal Bl 710b, the instant messenger program unit 220 of the terminal Bl 710b displays the message on the window of the instant messenger 720b in the form of an emoticon, and the communication program unit 230 converts the message into a toy robot command (refer to FIG. 5) and a toy robot control signal (refer to FIGS. 5 and 6) and transfers the converted signals to the toy robot B2 700b.

[81] Subsequently, the toy robot B2 700b expresses the counterpart's melody message as a motion or a sound through the control unit 410, driver unit 430, and sound output unit 460 in response to the robot control signal. [82] Referring to FIG. 9, if the instant messenger 820a of the terminal Al 810a transfers an alarm message (7 alarm 0700a') to the instant messenger 820b of the terminal B 1 810b, the instant messenger program unit 220 of the terminal Bl 810b displays the message on the window of the instant messenger 820b in the form of an emoticon, and the communication program unit 230 converts the message into a toy robot command (refer to FIG. 5) and a toy robot control signal (refer to FIGS. 5 and 6) and transfers the converted signals to the toy robot B2 800b.

[83] Subsequently, the toy robot B2 800b expresses the counterpart's alarm message as a motion or a sound through the control unit 410, driver unit 430, and sound output unit 460 in response to the robot control signal (i.e., according to a time set for an alarm).

[84] Although the present invention has been described with reference to several preferred embodiments, the description is illustrative of the invention and is not to be construed as limiting the invention. Various modifications and variations may occur to those skilled in the art, without departing from the scope of the invention as defined by the appended claims. Industrial Applicability
